Stumbled upon this piece of awesomeness via lyle's awesomeness. I was wondering if anyone had any idea why they are advocating high glycemic sources of carbs (potatos and rice) when the article was referring to insulin sensitivity being beneficial for protein synthesis. Wouldn't such high glycemic carbs eventually lead to less sensitivity, or is the timing (the vast majority coming in the two meals following your workout) counter the carb influx? I may be completely off in this and would live more info!

You only screw up insuiln senitivity with chronically elevated insulin levels. A couple spikes will not do it so it's the timing that makes it irrelevant. Also hard training athletes who are lean are not going to get insulin resistsant. tha'ts only an issue for sedentary fat people.
